Red Hat: Jcat, OpenShift, Ceph and CCSPs

Red Hat
  • Initial release of Jcat

    Today I released the first official tarball of Jcat, version 0.1.0. I’ve started the process to get the package into Fedora as it will almost certainly be a hard requirement in the next major version of fwupd.

    Since I announced Jcat a few weeks ago, I’ve had a lot of positive feedback about the general concept and, surprisingly, even one hardware vendors suggested they might start self-signing their firmware before uploading to the LVFS (which is great!). More LVFS announcements coming soon I promise…

  • Jcat 0.1 Released As Alternative To Microsoft Catalog Files

    Jcat is an open-source alternative to Microsoft Catalog files and was started as a format for handling arbitrary signatures for external files. The initial focus is on the Fwupd/LVFS use-case in ensuring BIOS/firmware files are not tampered with prior to flashing on the local system. Jcat is a JSON-based file format with Gzip compression and contains a set of detached signatures.

  • Red Hat OpenShift 4 and Red Hat Virtualization: Together at Last

    OpenShift 4 was launched not quite a year ago at Red Hat Summit 2019. One of the more significant announcements was the ability for the installer to deploy an OpenShift cluster using full-stack automation. This means that the administrator only needs to provide credentials to a supported Infrastructure-as-a-Service, such as AWS, and the installer would provision all of the resources needed, e.g. virtual machines, storage, networks, and integrating them all together as well.

    Over time, the full-stack automation experience has expanded to include Azure, Google Compute Platform, and Red Hat Openstack, allowing customers to deploy OpenShift clusters across different clouds and even on-premises with the same fully automated experience.

    For organizations who need enterprise virtualization, but not the API-enabled, quota enforced consumption of infrastructure provided by Red Hat OpenStack, Red Hat Virtualization (RHV) provides a robust and trusted platform to consolidate workloads and provide the resiliency, availability, and manageability of a traditional hypervisor.

  • Ceph Gets Fit And Finish For Enterprise Storage

    Ceph, the open source object storage born from a doctoral dissertation in 2005, has been aimed principally at highly scalable workloads found in HPC environments and, later, with hyperscalers who did not want to create their own storage anymore.

    For years now, Ceph has given organizations object, block, and file-based storage in distributed and unified cluster systems well into the tens of petabytes and into the exabyte levels, storage that takes high levels of expertise to deploy, run, and manage. Building and managing these massive object storage clusters takes the kind of skills that HPC, hyperscaler, cloud builder, and other service providers tend to have. But large enterprises and many Tier 2 and Tier 3 service providers do not have such skills. And the workloads they need to run – either themselves or on behalf of clients – is driving demand for object storage among more mainstream enterprises, who want to leverage artificial intelligence, analytics, containers, and similar advanced technologies but who do not have the expertise to manage complex Ceph environments.

    Red Hat is looking to fix that. The company, a unit within IBM, has recently rolled out Red Hat Ceph Storage 4, with the goal of bringing petabyte-scale object storage to cloud-native development and data analytics workloads that are becoming more commonplace among enterprises and can take advantage of cloud-level economics. It also will help Red Hat broaden the markets for Ceph.

  • Tech Data, Ingram place bets on hybrid cloud with Red Hat

    Open source cloud services may be the next big seller for the local channel after Red Hat appointed two new distributors and pumped more resources into ANZ.

    Tech Data and Ingram Micro have been appointed as distributors for the Red Hat Certified Cloud and Service Provider (CCSP) program and will work with Red Hat to qualify, recruit and on-board partners as CCSPs.

    Red Hat said the new local push comes in response to increased interest in managed, multi-hybrid cloud solutions in Australia and New Zealand.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
